BESILIENT VEHICLE-WHEEL.

Specification of Letters Patent. I Patented MarQll, 1916.

Application'filed June 8, 1914. Serial No. 843,649.

To all whom it may concern:

Be it known that I, SAMUEL J OHNSTONE, a citizen of the United States, residing at Sacramento, in the county of Sacramento and State of California, have invented certain new and useful Improvements in Resilient Vehicle-Wheels; and I do declare the following to be a clear, full, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in wheels and particularly to a device adapted to embody asupporting structure comprising a continuous rubber resilient member formed in one piece with an integral outer rubber rim, the supporting structure to be placed between a channel shaped rim on. the telly of the wheel and such integral rubber rim, said rubber rim having side plates slidable over the sides of the channel shaped rim in such a manner and with such construction as to cause the supporting" structure to sustain the weight of the telly and at thesame time afford ample resiliency and elasticity between -the inner and outer rims to compensate for and overcome the jolts and jars due to the wheels riding over un- I even surfaces.

The device is further designed to be securely protected from external, wear and cpntact, thus insuring a device which will be of durable construction and free from crystallization and one which will not be subject to the varying conditions due to expansion or contraction owing to heat or cold.

The device is further adapted to be disposed between the inner and outer rims unline XX of Fig. 1.

reference indicate corresponding parts in the several views.

Figure l is a side elevation, partly broken out, of a portion of a wheel showing my improved structure. Fig. 2 is a sectional View ofthe rim of the wheel taken relatively on a Referring now more particularly to the characters of reference on the drawings, the numeral 1 designates the hub of the wheel, 2, the spokes, and 3, the telly.

The numeral designates the channelshaped rim secured to the telly 3 and provided with the flush securing'pins or bolts 5 for holding the rubber structure into connection with said rim 4 in a manner as will presently appear.

My improved rubber structure comprises lapsing or being pressed too far down-" wardly between the side plates 7. The supporting rubber structure 9 is formed as a' component part of the contracted portion 6 and extends outwardly therefrom on each side to exactly -fit between the channelshaped rim 4 as shown clearly in a cross'section view in Fig. 2. This portion 9 is secured to the side plates 7 by means of bolts 8 and is secured at its inner end to the rim 4 by means of pins 5 threaded at 5 to screw into one side of the rim 4 and provided at its other end with a slot 5 to receive a screwdriver or' like tool, these pins 5 being prevented from coming out of position by means of the side plates 7 fitting thereover in the manner shown. The rubber struc-' ture is prevented from independent rotary movement within the rim 4 by means of lugs 10 secured to the channelshaped rim l-between which extend projectingflangcd members 10 on the supporting structure The rubber supporting structure 9, as can be plainly seen in Fig. 1, consists of webs extending diagonally from the rubber tire and arranged in pairs, the member of each pair intersecting each other and being formed into a component part at the intersection, the adjacent inner ends of adjacent radial movement of the outer rim, such bolts 8 moving into the recess 11 when this action takes place. The rubber construction 9 fits closely between the sides of the rim 4, in the manner shown in Fig. 2, which strengthens the device laterally, which is necessary for successful operation.

From the foregoing description it will readily be seen that I have produced such a device as substantially fulfils the objects of the invention as set forth herein.

While this specification sets forth in de tail the present and preferred construction of the device, still in practice, such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claim.

tire spaced from said channel shaped rim.v and provided with side plates movable over the sides of said channel shaped rim, a rubber supporting structure interposed between said solid tire and saidchannel shaped rim, such rubber supporting structure comprising webs extending diagonally from the rubber tire and arranged in pairs, the members of each pair lntersectlng each other and being formed into a component part at the intersection, the adjacentinner ends of adjacent pairs being formed into component members provided with projecting flanges and means on the channel shaped rim engageable with said flanges to prevent inde pendent rotary motion of the said rubber tire and supporting structure, as described. In testimony whereof I affix my'signature in presence of two witnesses. SAMUEL J OHNSTGNE. Witnesses:
